Have you tried the Emergency service approach with Apple? Perhaps if they
knew that the IPHONE can be used as another tool in the HAMS toolbox for
helping to provide emergency services, and it your app was free, they might
listen.
Do you have a contact you are dealing with at APPLE? Maybe we could all
write them. I love my IPHONE and anything that can use the GPS for position
reporting especially in an emergency would be usefull.

findU uses http, once you have an account you can enter your position
by just sending a URL like
http://www.findu.com/cgi-bin/inputpos.cgi?call=k4hg-8&passwd=xxx&lat=24.7727
6&lon=-80.94058
I wrote a client for the iPhone that reads the GPS and sends it to
findU, unfortunately Apple does not feel that it has a wide enough
audience to justify making it available through the App store. Unless
tApple lowers the bar it will never see the light of day. Keep that in
mind if someone chooses to do a client for your API. You need to lie
to Apple about the audience, mention ham radio and the answer is no.
